The term "transgender-mtf" in a porn video context refers to content involving a transgender woman, also known as MtF or male-to-female. This typically means that the performer was assigned male at birth but now identifies and presents as a woman. Such videos often showcase gender transformation processes, hormone therapy outcomes, and various sexual experiences involving trans women. The tag is used to inform viewers about the content they are about to watch and help them find specific types of adult material they may be interested in
